I To all whom it may concern:

Be it known that 1. JOHN Konn- HnPr, a citizen of the United States, anda resident of the city of Chicago; county of Cook, and State ofIllinois, have invented certain new and useful Improvements n CarcassScraping and Cleaning Mechanisms and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of this specification. v

The present application-constitutes a division of my prior applicationfor patent, for

, carcass scraping and cleaning. mechanisms,

Serial No. 384,287,filed J My 17 1907.

i This invention relates to improvements in scraping mechanisms andparticularly to that classadapted for scraping, polishing and cleaiiiighogs.

. Heretofore in carcass scraping machines the carcasses have beensupported on or suspended from a suitable conveyor and passed betweenscraping devices suitably arranged to act thereon. Where the carcassesare supported lengthwise on the conveyer there has always been a stripextending the entire length the carcass that could not be acted class ofmachine in which the carcass is suspended by hooks there is always a'portion where the hook engages that is not scraped. Eurthermpre machinesemploying conveyors which necessitate carriages and hooks being used forengaging the carcasses are quite expensive to install, requireconsiderable space, constantly need repairing and consist of a cassescan be dispensed 'with.

' "Also the hog scraping mechanisms heretofore have only been adapted toclean the carcass and have-not in any way aided in forcfingthegcarcasses-through themachine.

carcasses are continuously rotated or turned, 7

thereby exposing all parts to the action of the scrapers and to providea scraping device in which it is practically impossible to dislodge acarcass while being acted upon by the boaters. a

It is also an important object of this invention to provide a machine inwhich flexible scraping mechanisms are employed and in which thescraping mechanisms coact with the aforesaid conveying or moving androtating mechanism for rotating and forcing the carcasses through themachine.

It is also an object of this invention to provide a device of the classspecified in which the rotating and moving carcasses are partlysubmerged in fluid at a suitable temperature whereby the hair, dirt, andrefuse provide a device in which the carcasses are, i

if necessary, further scalded while being acted upon by the scrapersshould they not have been properly scalded in the scalding vat ;or tankbut entirely eliminating the use of igspraying and pumping devices. Itis also an object of this invention to provide a device in which thecarcasses are delivered anism and a gravity exit therefor afterscraping.

a It is a further object of this invention to provide a highly eificientand g'reatly'simplified machine of both small and great caby gravity tothe moving and rotating mechpacity and the capacity depending upon the Iavoided and which requires a minimum number of attendants. a

The invention consists of the matters.

-'therethrough from the oonveyer a.

On the drawings: Figure 1 is a longitudinal vertical section of a deviceembodying my invention, with the scraping mechanisms arrangedtransversely the travel of the carcass. Fig. 2 is a topplan viewthereof.

As shown in the drawings: A, indicates a scalding vat or tankconstructed of any suitable material and size anddiaving the rear bottomwall, a, thereofpinclined upwardly and rearwardly. Journaled in thesides of the tank at the upper and lower ends of said inclined wall a,are shafts a'a on which the elevator 11?, is supported. Adjacent therear end'of said scalding tank A, is a water tank B, provided withsuitable water inlet 6, and steam or heating fluid inlet b, and with asuitable washout pipe or plug 6.

' Said tank B, is constructed of sheet metal orany other preferredmaterial and comprises a bottom wall 6 side walls I); and end walls bb,of a height, width and length to c'ontain the various mechanismstherein. The wall 6, of the tank B, is placed against the top of theinclined wall a, of the scalding vat and is provided with a swinging orautomatically'closing door b, above the top of the inclined wall of thescalding tank, which is of a length to admit the hog lengthgise 'idlsecured to the-side walls I), and end wa l b", of said tank is aninclined platform 5, which extends rearwardly from the bottom of thedoor opening and the lower end thereof is directed horizontally or at aslight angle upwardly. Journaled in the side walls 6", of said tank B,is a beater shaft C,

on which are bolted or otherwise rigidly se-' cured flexible beaterarmsc, constructed of any suitable material such as canvas, chains,

v the outer ends of said heater arms 0, are a plurality of sets offlexible or. rigid blades c -c0 having their outer ends'curvedoutwardly, and, as shown, arranged two abreast but obviously any numbermay be used in a set. l

- Journaled in suitable hearings in the side walls 6 below and at therear of the beater shaft C, is a roll, drum or cylinder D, to which arerigidly secured in any preferred manner bars or plates (1, of suitablemetal or other material, which are shown as angle irons securedto theroller by one flange, and the other flange is directed radiallyoutwardly and parallel the axis of the drum. It -15 to be distinctlyunderstood that in the construction shown, any form of roll or drum maybe used and either flexible or igidbars 0r ribs may be used with anyswinging doors mayrclose said exit.

form of drum. The specific construction used'depends entirely upon thespecific demands of the user, e: 9., for a large slaughter house a metalcylinder may be used with.

teel ribs which are slightly flexible to yield should the machineoperate above a given velocity, or a yielding cylinder may be used suchas a solid canvas or rubber cylinder, and either yielding ornon-yielding ribs. On the other hand. in the smaller plants where onehog is operated on at a time, either a metal or other cylinder may beused with ,7 either yieldingsor non-yielding ribs, and thev constructionfor any user may vary to meet the exigencies of the specific case.

A su table driving pulley D, is secured the drum shaft (1, atone end andsprocket M wheels (F-(Z are rigidly secured to the beater shaft 'anddrum shaft 61 of the drum D, outside and at the-opposite side of the.tank. and a chain (1", is trained there around, whichdrives the beaters.

Above and slightly -to the rear of the center of the roll or drum D,just suiliciently for thobars (I, to pass, is-a platform'di which isshown-us horizontal to the endwall 71", of the tank'and is then inclineddown If of the tank B, above the platform (i and pivoted thereto is adoor 6, curved toward the opposite end of thetank and rear,

A cable orc'ord e trained around suitable pulleys e e *e is secured "to" the latche, and extends w thin convenient reach of an 'attendantfor'opening thedoor to admit the cleaned carcass through the opening in the end wall 6upon'the platform X, and if desired a suitable strip of flexiblematerial G, "s'uch 'as canvas or The b.-1nds,s'traps or bars are made'ofmaterial such as .steel, rubber orothe r suitable m terial. the objectof which will be hereinafter described; The operation is as follows: The.hogs, after being suitably scalded. in the vat or tank A. are moved.upon the elevator of, which delivers them through the door I), and thecarcasses move by gravity to the end of the platform. bfiand upon theroller D. Inasmuch as the-bars-tl, are parallel with the axis of theroller upon rotation thereof the bars at each revolution engage the hogand rotate or turn the same continuously. The hog is not movedlongitudinally, inasmuch as the roll or drum is not spiral and thescrapers whichrotate ,opp'ositely from the direction of rotation of thedrum P e s r t e eras-se V onghly cleaned, the cord enamel the carcassesthe same is being rotated. The beameprevent the carcass from beingthrown rearwardl from the. rotating drum and the rigid door. e, preventsthe carcass from being moved by the heaters forwardly beyond the roll,so that at all times the carcass is contimlously spinning at a high rateof speed in position for thebeaters to act continuously on all partsthereof. The door a has a-lower projecting edge which also serves toscrape and dehair the rapidly r0 tating carcass. The water level'in thetank may be any preferred height, blit is shown slightly above theroller D, approximately on a level with the middle of the carcass sothat the carcass is lying androtating in water (which is heated or not,as found necessary) and the heaters acting thereon not only scrape thebristles therefrom, but polish the carcass. After the carcass is thoringthe catch and opening the door and the, carcasslis forced upon theplatform 0!, and is delivered by gravity upon the operating table. orbench X. The cord is released, and

' the operation repeated.

It is seenthat the and pumps are eliminated, and that the carcase isWashed clean as it is rotated continuously in water. Furthermore, shouldthe carcasses not be sufiiciently sca-lded for remoral of the bristle,the carcass may again be scalded in the tank as the scrapers actthereon. v Many changes of construction may be varied. without departingfrom the principles of this invention, and I therefore do not desire tolimit this application for patent as to details, or otherwise thannecessitated by the prior art.
